Power Surge

We got a call for a customer’s monitor showing “out of range“. This is all the customer could see. We were able to use ScreenConnect and we could see the desktop fine, so it must be the monitor.

One suggestion was to go to “msconfig“, in the “boot” tab, check “base video“, and reboot.

This got the user to be able to see their monitor; however, when we tried to set the resolution to what they had before the monitor went black again with the warning “out of range”. Since we were connected remotely we could see the desktop and make the changes to get desktop visible again. A tech went on-site.

The tech had an extra DVI cable in the vehicle and swapping the cable totally fixed the issue. We think a recent power surge there may have caused the issue.
